To be entirely realistic I wouldn't make it. If it wasn't for some pretty severe mental problems stemming from brain damage, which seem to be getting worse, I'd probably do okay. I don't have any farming skills or anything but actually do have some rather interesting training and knowlege. Sadly though without civilization to manufacture drugs, I'm wise enough to realize my problems would be my downfall in the best of situations I suspect (who knows, I could be wrong). At the least I've been getting softer and fatter every day as well (and I've been in retirement for a while).
Strictly speaking I do not think civilization would fall apart instantly in most "apocolyptic" type situations. Humans are nothing if not social creatures and even with technology out of the equasion we have enough infrastructure where I think people would still pull together under what is left of our leadership.
Of course then again I'm assuming a pseudo-apocolypse here as opposed to something that actually kills us all outright. If say for example earth is hit by an unusually uber-solar flare that burns off the atmosphere or something like that, all life ends. It doesn't matter who you are. Our only way of surviving as a species would be if we had mastered space travel and colonized elsewhere (which is one of the reasons I'm so hot on that idea, and things leading to it).
